Fifteen samples of a shallow profile Sverrefjellet Volcano, located in the NW part of Svalbard - Bockfjord region were pollenanalysed. Frequency of pollen grains, spores and NPP was quite low. Only the local taxa produced pollen in greater abundance. The pollen spectrum was considerably varied, although pollen grains and spores of most taxa were present in low abudances. This was due to low pollen and spores productivity of the Arctic flora, which propagates mostly in a vegetative way. To obtain as much information from the profile under study as possible, we analysed the non- pollen palynomorphs as well. We succeeded above all in determination of eggs, buccal tubes and claws of the Tardigrada phylum. The determination has beeen recently verified by specialists (prof. L. Kaczmarek and dr. M. Roszkowska). The results of the pollen- and NPP analysis are presented in polllen- and NPP diagram, which represents a picture of the species- poor Arctic flora.
